CLEANING MEGHANISM.

App1cation filed May 9,

drawings, and to the numerals of reference marked thereon, which form a part of this speciicatlon.

This invention relates to a cleaning mech M anism, and particularly to a mechanism which is adapted to clean excess cement from rubber clothing and other water-proof goods during the process of manufacture thereof. In the manufacture of rubber clothing adjacent pieces of rubber cloth are joined together by cemented seams and it is desirable that the excess cement be removed before the finished article is used commercially. p

It is an object therefore of the present invention to provide a cleaning mechanism wherein rotary cleaning members are adapted to remove excess cement and similar material from rubber clothing and other waterproof goods.

It is another object of this invention to provide a cleaning .mechanism wherein freely rotatable cleaning members are carried by a continuous movable conveyor and moved thereby over a surface to be cleaned.

It is a further object of this invention to provide a portable cleaning mechanism having freely rotatable cleaning members and a power drive for advancing said cleaning members over a surface to be cleaned.

It is also an object of this invention to provide a mechanism for cleaning excess cement from the seams of rubber cloth, said mechanism being adapted to operate without disturbing the remainder of the cloth.

It is an important object of this invention to provide an eflicient and simple power driven cleaning mechanism which operates to rapidly remove excess material such as cement from the seams of rubber clothing.

Other and further important objects of this invention will be apparent from the disclosures in the drawings and the specification.

The invention (in a preferred form) is 1921. Serial N0. 467,913.

illustrated in the drawings and hereinafter more fully described.

On the drawings:

Figure l is a view in elevation of a cleaning mechanism embodying the principles of this invention.

Figure 2 is an enlarged fragmentary top plan view of the mechanism with parts in section.

Figure 3 is a section on the line 3-3 of Figure 2 with parts removed.

As shown on the drawings:

The cleaning mechanism of this invention is supported above a working surface 1 by means of a bracket 2 which is secured to i said working surface by means of bolts a. Pivotally mounted in said bracket 2 is a sleeve 4 which rotatably supports a driving shaft 5 journalled therein in bearings 6 and adapted to be driven from any suitable source of power through a pulley 7 which is secured to one end thereof and which is adapted to have a belt 8 leading to the source of power engaged thereover. Secured to the outer end of the sleeve 4 is an angle bracket 9 which acts to support the cleaning mechanism of this invention. Said mechanism which is driven through a double sprocket 10 secured to the outer end of the shaft 5 will now be described. Abutting the outer face of the angle bracket 9 and secured thereto is a frame plate 11 which is apertured to receive the inner end of the reduced portion of the shaft 5 and a reduced boss 12 on the sprocket 10.

Engaged through an aperture in the outer end of the angle bracket 9 and through a registering aperture in the frame plate 11 is a bolt or stub shaft 13 which has rotatably mounted thereon a double pulley 14 which is in alignment with the double sprocket 10. Engaged over each side of the sprocket 10 and the corresponding side of said double pulley 14 is a sprocket chain 15 which acts to rotatably support the cleaning members. Said cleaning members are pivoted on shafts 16 which are integral with connecting pins which connect certain links of the sprocket chains 15 and consequently the cleaning members are independently rotatable between the sprocket chains and adapted to be advanced thereby over a surface to be cleaned. Said cleaning members comprise grooved rollers 17 which are preferably constructed of wood or aluminum and the grooves of which are preferably filled with unvulcanized rubber 18 or a similar material which will act to pick up the excess cement.

In order that the chains l5 may be enclosed, a guard plate 19 similar to the frame plate 1l is supported on the outer end of the bolt 13 and on a boss 2() on the double sprocket 10 and is secured in position by means of nuts 21 and 22 secured to the bolt 13 and the outer end of the drivingshaft 5 respectively.

The cleaning mechanism is particularly adapted to operate to remove excess cement from a seam 23 which joins together two pieces of rubber or water-proof cloth 24 and Q5. Said cloth is laid on the working surface 1 and the cleaning mechanism'is lnormally held away from the seam by means .of a coil spring 26 which is engaged between the sleeve 4 and said working surface. lIt is, of course, apparent that by applying downward pressure to thesleeve 4L, said coil spring 26 `will `be compressed and the cleaning mechanism `briiught into contact lwith the seam 23. The `rotation of. the .shaft 5 acts to drive the lsprocket 10 to ladvance .the chains 15 andthe cleaningrollers 18 are thus advanced along the seam to remove the eX'- cess cement therefrom. Due to the fact that these cleaning rollers are independently rotatable, the remainderfof the cloth is .no-t disturbed and dueto thefact that a plurality of these rollers are continuously in contact with the seam,.aneliicient 1and rapid removal of the excess cement or other material is effected.`

The mechanism lmay be manually moved over the cloth, or cases where heavier and larger cleaning ymechanisms are used, the same will act to automatically move the cloth along on the table due to the frictional contact of the advancing rollers therewith.

I am aware that numerous details of `construction may be varied through a wide range without departing from the principles ofthis invention, and I therefore dc not purpose limiting the patent granted otherwise than necessitated by the prior art.

I claim as my invention:

1. A mechanism of the class described comprising a power drivenconveyo-r and .independently rotatable soft surfaced cleaning members carried. thereby and adapted to make rolling contact with a surface vto be cleaned.

QjA mechanism of the class described comprising a continuous conveyor and a plurality of separately pivoted soft surfaced cleaning rollers carried thereby and adapted to make rolling contact witha surface to be cleaned.

3. A mechanism of the class described comprising a frame, a sprocket on the frame, a rotatable means onthe frame in alignment with the sprocket, a chain driven by the sprocket and engaged over the rotatable means, and a plurality of rotatable cleaning members having a relatively soft surface carried by the cha-in ,andadapted vto make rolling contact with a surface to be cleaned.

4. AV mechanism of the class described comprising a frame,I a sprocket on the frame, rotatable means on the frame in alignment with the sprocket, a chain driven by the sprocket and engaged over the rotatableV means, a plurality of freely rotatable cleaning members carried by the chain and adapted to make rolling contact with a surface to be cleaned, and a power ,drive for the sprocket.

5. A mechanism of the class describedl comprising aframe, a sprocket o-n the frame, rotatable means on kthefframe in alignment with the sprocket, a chain driven by the sprocket and engaged over the `rotatable means, and independently rotatable softsurfaced cleaning. rollers carried byV thechain and adapted tomake .rolling contact .witha surface to be cleaned.

6. A cleaning mechanism for Vremoving excess cement, comprising freely rotatable cleaning members adapted to remove the cement, a conveyor therefor` `power driven vmeans connected thereto yfor advancing the cleaning members. i

` A cleaniv mechanism oftheclass described co-mprising. a driven shaft ,pi-votally mounted above a surface to be cleaned, cleaning means comprisingua pluralityr of rollers supported on theshaft and, ydriven therefrom, and compressible `means associated with the shaft for normally holding the cleaning means vabo-ve the surface tov be cleaned. Y

V8. A device of the class describedcomprising power traversed soft surfaced cleaning means mountedA above a surface to be cleaned, and yieldable means for normally holding the cleaning Ameans above the'surface to be cleaned.

In testimony whereofI have hereuntosubscribed my name inthepresence of two sub- Y scribing witnesses.
